HEATER FOR CHIMN`EYS.

Specification forming part of Letters Patent No. 53,770, dated April 10, 1866.

To all whom it may concern Be it known that we, THOMAS M. AsPrN- ALL and STEPHEN H. WHITLooK, of Piqua, in the county ot' Miami and State of Ohio, have invented a new and useful Improved Heater and Fuel-Saver and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon; and We do hereby declare that the following is a full, clear, and exact description of the construction and operation of the saine, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a perspective View; and Fig. 2

'is a bisected View, representing the inside of the box, Fig. l.

The improved heater and fuel-saver consists of a box of any convenient size to snit the chimney in which it is proposed to be inserted, and may be made of zinc, sheet-iron, or any suitable metallic substance; but it is recommended that the bottom be of cast-iron, which is to be of a concave form, as represented by D, Fig. l. From this concave bottom is an aperture or flue, as represented by A a, Fig. l,

. 2. For the purposes of durability it is recommended that this flue be made of cast-iron.

There is an aperture near the bottom of the box, as represented by B, Fig. 1, to admit cold air, which is heated by means of the concave bottom D and the flue A a. The cold air on entering the box at B, Fig. l, is forced to pass between the concave bottom D and the iue a and becomes immediately heated, when it passes ont at the opening C, Figs. l and 2, and is conducted by means of pipes to any chamber in the house.

This heater or box, Fig. l, is to 'be placed immediately over the arch-bar and in the throat of the chimney, so as to force all the heat or" the fire in the chimney to strike the concave bottom D or pass through the ue A, the flue carrying off all the smoke.

We claim- The arrangement of the heater or box for insertion in the chimney above the arch, and provided With a flue, A aA, for the passage of the heated air, &c., from the fire, a cold-air induction-openin g, B, and a Warm-air delivery, C, substantially as described and represented.
